The Modern Evolutionary Synthesis.

Evolutionary Relationship

Modern plants and animals resemble fossils found in the same area.

Some specific modern-day social issues related to evolutionary psychology include mate selection preferences, parental investment, aggressive behavior, altruism, and gender differences in behavior and cognition. Evolutionary psychology can provide insights into how these behaviors and preferences have evolved to increase reproductive success in our ancestors and how they manifest in contemporary society.

Eohippus, meaning 'dawn horse' in Latin, is generally considered the oldest known evolutionary ancestor of today's modern horse.
